FAQ
- How does the INS maintain position accuracy without GNSS input?
- A: The system uses pre-calibrated IMU error models and dynamic Kalman filtering to correct for drift, maintaining position error growth <0.1m/h (CEP) in pure inertial mode.
- What is the typical drift rate in pure inertial navigation?
- A: Pure inertial drift rates are <0.1/h (heading) and <0.1m/h (position CEP), with optimized error growth modeling for long-term stability.
- How does GNSS/INS fusion improve accuracy?
- A: Tightly coupled fusion reduces errors by 90% in dynamic conditions (e.g., 0.1m horizontal/vertical accuracy vs. 1m without fusion).
- Which factors cause position error growth over time?
- A: Primary factors include gyro bias, accelerometer noise, and installation misalignment. The system mitigates this via continuous calibration and Kalman filtering, limiting drift to <100m/1h (CEP).
- What is the navigation update rate?
- A: The system supports 400Hz-1000Hz IMU data sampling and navigation solution updates, ensuring real-time control loop integration.
- Can it operate in GNSS-denied environments?
- A: Yes, with a standalone INS mode maintaining centimeter-level accuracy for up to 10 minutes (1km/h drift), supported by anti-jam algorithms.
- What is the attitude accuracy?
- A: Heading, Pitch, and Roll are stabilized to 0.01 precision via multi-axis IMU fusion.
- How does the system handle installation misalignment?
- A: Factory pre-calibrated lever arm parameters and mounting angle correction tools compensate for 0.1 alignment errors, ensuring accurate positioning.
- Which interfaces support multi-sensor integration?
- A: Supports COM1/COM2 (UART), CAN bus (J1939), SPI, and PPS for IMU/barometer/magnetometer integration.
- What is the power consumption?
- A: Typical power consumption is <1W, with standby mode <0.5W, making it suitable for battery-powered UAVs or mobile robots.
